When experimenting with or extending protocols, it is often necessary
to use some sort of protocol number or constant in order to actually
test or experiment with the new function, even when testing in a
closed environment.  This document reserves some ranges of numbers
for experimentation purposes in specific protocols where the need to
support experimentation has been identified, and it describes the
numbers that have already been reserved by other documents.
